When medicines are taken as directed, they can greatly improve your health. But if they are not taken as instructed, they may not work. In some cases, not taking them correctly can be harmful. To help make sure that your treatment remains effective and safe, understand your medicines and how to take them.

Medicines can interact with one another. They can also interact with herbal remedies and supplements. In either case, it can be harmful to your health. This is why your doctor needs to know about every medicine, vitamin, herb, and supplement that you take. Schedule a visit with your doctor or pharmacist to discuss all your medicines. Besides pills, your doctor also needs to know about medicines for your skin (topical), such as oils, creams, and ointments. They also need to know about eye drops. Also, tell your doctor about medicines that you take only occasionally and about any over-the-counter (OTC) medicines. When you go in for your visit, bring one of these:

• A bag filled with bottles of all your medicines. Include all prescription and OTC medicines. Also include any vitamins and herbal remedies that you take. Keep medicines in their labeled bottles.

OR

• A list of all the prescription and OTC medicines, vitamins, herbs, and supplements that you take. Be sure to list how much you take and how often you take them.

Your doctor or pharmacist will review your medicines with you. They can figure out if you are at risk for any medicine interactions. Depending on what you take, your prescriptions may be adjusted.

Some questions to ask your doctor include:

• Am I taking any medicines I no longer need?
• How long should I take each medicine?
• What are the side effects that should be reported?
• Do any of the prescriptions and OTC medicines interact with each other in a way that will cause problems?
• Are there any foods or drinks I should stay away from?
• Are there any OTC medicines that I should stay away from because of my current medicines or because of my health condition, such as OTC nasal decongestants or high blood pressure ?

Remembering to take medicines on time can be hard. Here are some tips to help you:

• Develop a routine. For example, take your medicine at the same time each day, such as after you brush your teeth. This helps remind you to take it.
• Schedule reminders on your computer, watch, or cell phone.
• If you take more than one medicine, use a pillbox. Get one that lists the days of the week. If you take pills more than once a day, get a pillbox that has spaces for morning, noon, and evening. As you fill the pillbox, have the bottles with labels in front of you. This helps to prevent confusing pills that look alike.
• Keep your medicine routine when you're away from home. When traveling, make sure you bring enough for your entire trip plus 3 to 5 days of extra medicines in case of unplanned travel delays. When traveling by air, keep your medicines in your carry-on. Be sure you have your prescription labels (either the original package or a photocopy).

Follow up with your doctor. This lets them see how well you are doing on the medicine. It may take a few tries to find the right dosage, medicine, or combination of medicines for you. Make sure you talk with your doctor about the medicines you take and how they make you feel. And never stop taking a medicine without talking to your doctor first. Some medicines should not be stopped suddenly. Others can cause problems if they are not taken for the prescribed amount of time.

Below are some tips for taking medicine safely. If you have any questions about your medicines, call your doctor or pharmacist:

• Make sure to refill your prescription while you still have some left, so you don't run out. If you use mail order, be sure to order with enough time for the refill to arrive while you still have some left.
• Be sure refills are correct before taking them.
• Hold on to the instructions that come with each medicine.
• Don't take less than the prescribed amount to save money. Talk to your doctor if you can't afford your medicines. There are resources that can help you.
• Never share medicines.
• Never increase or decrease your prescription medicine or stop taking it before talking to your doctor.
• Store medicines in a cool, dry, dark place. A steamy bathroom is often not the best place.
